Yet another pair of young entrepreneurs are looking to capitalize on China's air quality problems.
Two sisters from Xining, the provincial capital of western Qinghai province, have launched an online business startup selling fresh air from the Tibetan Plateau. On their page, customers are asked to choose where they would like the air to be sourced from -- a mountain? a valley? -- though in a video about their project published by Pear Video they appear to be collecting air from a Xining park.
Each bag costs 15 yuan and the sisters claim that they have already sold 100 bags. However, they say that they are not in the air business for the money, but to draw attention to the need for better environmental protection efforts.

On Weibo, netizens are less convinced about the sisters' allegedly altruistic aims, pointing out flaws in their scheme and wondering how much damage they are doing to the environment by using plastic bags.
"Deceitful marketing. The air belongs to the Earth, how can you make it your private property and sell it off?" commented one netizen who said the very idea made him feel sick.
Of course, these two aren't the first to try to get China's choking city-dwellers to pay for more breathable air. Earlier this year, a Xi'an forestry department began selling off fresh air from the nearby Qinling mountains at 18 yuan a can. The project has received 200,000 yuan in government investment.
If you're in the market for some more high-end stuff, you can also pay a premium online for a breath of fresh Canadian or Australian air.(News from the shanghailist)
